100 = 10^2
1000 = 10^3
10000 = 10^4
0.1 = 10^(-1)
0.01 = 10^(-2)
0.001 = 10^(-3)
Now,
100 × 0.1 = 10^2 × 10^(-1)
= 10

the 3rd and 5th one
Step-by-step explanation:
The answer is the first option. 12m-12n
Answer:
<u>L = 12 inches and W = 8 inches</u>
<u>Area = 96 in^2</u>
Step-by-step explanation:
Perimeter(P) = 2(width) + 2(length)
Let W = width and L = length
P = 2W + 2L
L = 2W - 4
Substitute: P = 2W + 2(2W - 4)
P = 6W - 8
P = 40 inches
40 = 6W - 8
6W = 48
W = 8
L = 2W - 4
L = 2(8) - 4
L = 12
<u>L = 12 inches and W = 8 inches</u>
<u>===============================</u>
Check to see if this works:
P = 2W + 2L
P = 2(12) + 2(8)
P = 24 + 16
P = 40 inches <u>YES</u>
<u>========</u>
Area = WxL
Area = (12)*(8)
<u>Area = 96 in^2</u>
